IMPROVEMENT IN HYDROOARBOlii-BURNER TO ALL WHOM IT MAY OONOERN: l

Be'it known that we, ALPHO'NO W. 000K and ROBERT DMPSTR, of the citjr et' Buffalo, county of Erie,- and State of New York', (assignors to ourselves and J. S. Semen, et' thesame place,) have invented a certain new and improved Prctoleum-Gas Furnace; and we de herebydcclarc 'that the following is a -full, clear, and exact description thereof, reference boing hadto the accompanying drawings, making a part of this specification, in which-- i Figure I is a vertical section. Figure II is a top 'plan View. v Figure III is a transverse vertical section. The nature of this invention consists- First, in the constructionand use ofa retort, having -upon' the inside. thereof a'coil of pipe connected to the feed-tube, in combination with a common heating-furnace.

i Second, in a retort for'geuerating gas from petroleum, having a cored bottom with 111 air-Supply pip@- Third, in a retort for generating gas from petroleum, having a removable bottom plate, b v means of which sund or other sediment of the petroleum maybe read-ily removed.

Fourth, in a retort for generating gas from petroleum, having upon the inside thcreot` an open pan attached to the feed-pipe, and a discharged-pipe,connected thereto7 by means of which the tar or other sediment of the heavier qualitr of petroleum is collected and carried oii.

' Fifth, in the construction and use of a metallic plate forming the-top of a gas-generating furnace, which plate has one ox' more openings, for the suspension therein ot` one or more retorts, and a number of apertures for the introduction of the fuel.

Sixth, in the construction, application, and use of a feed-regulating chamber, and a strainer, the said t chamber being adjusted to the feed-pipe, and provided with hollow plugs or bushings for enlarging or diminishing the size of the boe of thc feed-pipe, and regulating the feed. Y

Seventh, in the combination, with a retort for generating gas from petroleum, ot a force-pump, which is attached to the 4feed-pipe, and may be used either for pumping lpetroleum into the retort (in ease feeding by atmospheric pressure is inconvenient or impracticable) or for forcing water into the retort for the purpose of generating steam therein. p

Eighth, the application and use of the. herein-described apparatus for generating steamrfor heating and other purposes.

Letters of like name and kind refer to like parts in each of the figures. v A represents a retort, which is suspended within the {ire-chamber of a furnace by means ofthe top iiange, n. 'lhe furnace B may be built of brick or cast iron, and is divided, by means of suitable partitions, into as many separate tire-chambers as there 'are retorts, so that the tire surrounding each retort may be fed and regu? lated separately. There may be one, two, er more tire-chambers and retorts, connected as shown in the drawings. Each ire-chamber has a drop-grate, Z1', as shown in Fig. III, which renders Vthe introduction of kindling and the starting of the fires more convenient.` i

The top 0f the furnace consists of a cast-iron plate, C, which is` provided with openings, C1, for the suspension therein ofthe retorts and apertures O2, with covers, C, for the introduction oi' the fuel. This top plate, C, may be made either in sections of the size of cach tire-chamber, or in one piece, covering two or more firechambers, a-srcprescnted in the draivings 5 The retort A is provided with acover, D, which is fitted on to the top thereof, and secured by means of the key all, passing through the tiro slotted standards' cl2, erected upon the iange al. The cover D, as well as the opening in the retort, is made beveliing, so that a more perfect and air-tight connection may be made. A draught-flue Eis lformed upon the top of the plate C, at a point where communicationcan lie-established with all the lire-chambers. :Dampers, E1, are placed therein, for regulating the lire in each chamber independent from the others.' f lhe smoke-stack E2 is 4connected to thisdraught-fluc, as shawnin the drawings.

F represents the feed-pipe, by means of which .the petroleum is conveyed into the top ot' the retort. -It passes through the cover, D, and a coil of gas-pipe, G, is connected to it upon the inside ot' the retort.l

For. the lighter qualities of petroleum, such as gasoline, dsc., this coil of pipe serves the purposeof converting the iluid'into avapor before it issues from the end of the pipe. When a heavier quality of petroleum is to be used, Athe coil of pipe is removed, and a dripping-pan, I-I, attached, which catches all of the iiuid; and as the tar or other sediment sinks to the bottom, it is carried oil` through the discharge-pipe nl.

I represents the feed-regulator and strainer, which is contained in an air-tight chamber, having a removable cover, which chamber is connected to the feed-pipe, asrshown at Fig. Il The feed is regulated, accordngto the capacity of the retort, with a given amount of heat, by-means of hollow plugs or bushings, il, which are` Yinserted'into the open end of the feed-pipe upon the inside of the chamber, as shown.

J represents a wire-gauze partition, placed diametrically within the chamber I, which serves the purpose of straining the iluid passing through saidchamber, and retaining all coarse dirt, sand, or other foreign matter.

The main pipe, which carries the gas generated in the retort into a gasometer, and thence into the building, is shown at K, and has a stop-cock, k1. It is connected to a blow-off pipe, L, having a stop-cock, Ll, upon its end, which blow-of pipe vis used for the purpose of cleaning the retort, as hereindescribed.

M represents a false bottom, which is placedA within the retort, and provided with a ring or handle, m1, by means lof which i-t may be lifted out through the opening at the top. i This is used for the purposeot` facilitating the cleaning of the retort. The most of the sediment ot' petroleum consists of a ne sandy substance, which settles up'on the bottom, and it' received within the false bottom, M, may be easily removed.

The bottom proper of the retort is cored out, an annular opening being formed as shown at n, which has an outlet at nl. A continuous current of air passes through the opening, which has the effect of preventing the wear of the bottom of the retort from excessive heat. The discharge-spout, for tlleescape of the'gas into the main pipe, is shown at O, and is cast on to the retort, as is also the outlet 1't,ex'tending outwardly through the brick wall of the furnace.

P represents a force-pump, which is connected to the feed-pipe upon that side ot' the chamber I which is opposite the bushing, il. This pump, in connection with the blow-olt` pipe L, may be used for cleaning the inside of the retort, as follows: Close the stop-cocks c in the main pipe, and X in the feed-pipe, and open the stop-cock Ll in the blow-oil` pipe; then place a basin of water under the pump, so as to immerse the lower portion thereof, (as shown by red lines in Fig. I,) and slowly force a fine stream of water into the retort. Steam Ais generated instantaneously, the force ot' which drives all fine sand or other sediment through the only outlet,` thc'blow-oii` pipe L. l

In the drawings we have represented a furnace large enough for four retorts, but we can also use one, two, or more retorts, according to the amount of gas to be generated. In case one or all of the retort's are not used for making gas, they can be used for generating steam without removing or altering any portion of the apparatus herein shown and described. I

What we claim as our invention, and desire to secure by Letters Patent, is-

1. The coil of pipe, G, in combination with the feed-pipe F and retort A, arranged and operatingsubstanf-ally as and for the purpose described.

2. The dripping-pan I-I and discharge-pipe h1, in combination with the feed-pipe F and retort A, for the purpose and substantially as described.

3. The plate C, having openings Cl and C2, in combination with the-furnace B, draught-liuc E, and retort A, constructed and arranged substantially as herein set forth.

i 4. The removable bottom plate M, in combination with theretort A', for the purposefand substantially as herein described. i a

5. The annular air-chan1ber n and outlet n,in combination with the retort A, for the purpose and substratimuy as herein described.

6.l The chamber I, plugs or bushings il, and strainer J, in combination with the feed-pipe F, for the purpose and substantially as herein described.

7. The combination of the force-pump I, feed-pipe F, and blow-oil` pipe L, for the purpose ofcleaning the inside of the retort A, substantially as described.

8. The application and'usc ofthe apparatus herein described, for generating steam, in the manner and f or the purposes substantially as herein set forth.
